Why Does Your Air Conditioner Smell Musty?

Why Does Your Air Conditioner Smell Musty?

The air conditioning system should filter dust, debris, and odors. When your air conditioner smells musty, the problem is most likely in your air vents. When mold or bacterial growth in the unit causes a damp odor, the air conditioner smells musty. You’ll need a professional HVAC technician to clean your unit or get a new ductless AC installation in Los Angeles.

What is The Root of The Musty Air Conditioner Odor?

Mold and mildew development are the most likely culprits if your air conditioner smells musty. However, your home’s musty odor could also be caused by bacterial development or a bug infestation. The most typical causes of an odorous air conditioner are as follows:

  • Mold spores and Mildew Growth

Mold prefers damp environments to develop, and your air conditioner’s condensate offers enough moisture for the fungi to flourish. Since moisture around vents can propagate spores more quickly, mold is frequently discovered in central air conditioner models.

In case of a leak, you may notice visual indicators in your ductless AC in Lawndale, such as water dripping down your wall.

  • Bacterial Colonies

Bacteria can frequently be discovered in standing water, such as in a full condensate pan or overflowing drain line. Like mold, bacteria give off musty scents, making your air conditioner smell terrible.

You may want to check your condensate drain line and pan if your air conditioner smells musty and damp. Bacteria may also be present in the evaporator coil and air filter. After draining the pan, clean the parts with a sanitizer. It will eliminate the odor and eliminate the microorganisms.

  • Pest Issues

Few people know that pests like roaches and rodents release pheromones with a musty scent. These bugs can take control of your air conditioner, leave feces, or shed skin that would smell bad. These excretions smell awful and can significantly lower indoor air quality, spread disease, and pose a health risk to the entire household.

If you have a ductless AC in Lawndale, it might occasionally happen that lizards or other animals enter your interior unit and cause discomfort.

How to Remove a Musty Odor?

  • Keep Your Cooling System Clean

Regularly cleaning your cooling system can be done at home. You may remove the filth from the air filter with some soap, running water, and a soft brush. A vacuum cleaner and some compressed air can be used to keep the evaporator coil free of dust, and a sanitizer can clean the outside of your air conditioner.

  • Regularly Apply Pest Control

A yearly pest control treatment should keep your air conditioner clean and odor-free if you reside in a region where different pests, such as rodents, roaches, mites, and other urban pests, are common.
